Jean-Pierre Sylvestre De Grateloup
Jean-Pierre Sylvestre de Grateloup (31 December 1782 – 25 August 1862) was a French physician and naturalist. He completed his medical studies at Montpellier and remained attached to the countryside of the southwest of France. In company with his childhood friend Jean-Marie Léon Dufour (1780–1865) and Dufour's friend Jean-Baptiste Bory de Saint-Vincent (1778–1846) he expressed his enthusiasm for botany specializing in the study of cryptogams, the ferns and other plants that reproduce through spores. Then the shells found in the region attracted his attention, in particular those from the Adour.Grateloup, "Tableau des coquilles Fossiles qu'on rencontre dans des terrains calcaires tertiaires (faluns) des environs de Dax" in ''Actes de la Société linnéenne de Bordeaux'', 183;: ''Mémoire de géo-zoologie sur les oursins fossiles (échinides) qui se rencontrent dans les terrains caleaires des environs de Dax'', 1836; Conchyliologie fossile des terrains tertiaires du bassin ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropods Described In 1840
The gastropods (), commonly known as snails and slugs, belong to a large Taxonomy (biology), taxonomic class (taxonomy), class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class (biology ...

Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=995130 on 2020-09-30 Distribution These large, split-sole snails are found in Tanzania, Madagascar, the Mascarenes, the Comoros and South Africa. 95-99% of ''Tropidophora'' species are endemic to Madagascar. Species The present classification of this genus into three subgenera, 95 species and 142 varieties is complex and confused. This classification is best ignored temporarily, as it is based on subtle morphological varieties among small samples. It is also assumed that many smaller species remain to be discove ...

Ludwig Karl Georg Pfeiffer
Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botanist and conchologist. Early life, Education & Medical Career Louis Pfeiffer was born in Cassel, the eldest son of the jurist Burkhard Wilhelm Pfeiffer and his wife Louise (née Harnier). Pfeiffer received his primary education in the Cassel Lyceum, where he distinguished himself academically, and by the age of fifteen was already at the top of his class. In 1820, political tensions forced his father to relocate the family to Lübeck, but Louis continued to excel, reaching the top of his class there as well. At the age of sixteen, Pfeiffer entered into university to study medicine, first at the University of Göttingen, and finally at the University of Marburg, where he studied under such prominent scientists as Georg Wilhelm Franz Wenderoth and Ernst Daniel August Bartels, graduating in 1825.Hodvina, Sylvain.

Latin Language
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four v ...

Type Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pomatiidae
The family Pomatiidae is a taxonomic family of small operculate land snails, terrestrial gastropod mollusks that can be found over the warmer parts of the Old World. In the older literature, this family is designated as Pomatiasidae. This family is a lineage closely related to the Littorinidae (periwinkles) common in coastal habitat. They have adapted to terrestrial life and are thus sometimes called "land winkles". They are defined by a chalky operculum at the rear end of the body, the shape of their thick shell and their mouth and a characteristic spiral sculpture. The sexes are separate and can sometimes be recognised because the female shell is slightly larger than the male shell. Taxonomy According to the Taxonomy of the Gastropoda (Bouchet & Rocroi, 2005), the family Pomatiidae consisted of two subfamilies: *subfamily Pomatiinae Newton, 1891 (1828) - synonyms: Cyclostomatidae Menke, 1828; Cyclotopsinae Kobelt & Möllendorff, 1898; Ericiidae Wenz, 1915 *subfamily Annu ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
